This base-mounted end suction pump integrates a cast iron casing and a bronze impeller with a stainless steel shaft and shaft sleeve. The dry shaft construction eliminates contact between the circulating fluid and the rotating shaft, supporting operation at 125 PSI. A mechanical seal constructed of ceramic and EPT rubber manages internal pressure and fluid isolation. This centrifugal single-stage pump utilizes gauge ports at the suction and discharge connections for system monitoring.
Operating with a 7.5 HP Premium Efficiency TEFC motor at 1750 RPM, this unit incorporates Aegis grounding and utilizes a 380-460V / 3PH power supply, achieving a DOE PEI of 0.45. The 'S' in the SCI series denotes Taco's advanced Self-Sensing technology, which eliminates remote sensors and field wiring by using internal mathematical algorithms to calculate system resistance and automate variable flow. The included VFD is configured with a fused disconnect without bypass and holds an enclosure NEMA 12 / IP 55 rating. The drive ships unmounted for customer wall installation without a bracket, harness, or vibration mounts.
